An in-flight magazine on board an Air China flight warning passengers to be wary of London's Indian, Pakistani and black population has caused outrage for being "blatantly racist".
The magazine told visitors to "take precautions when entering areas mainly populated by Indians, Pakistanis and black people" and urged people not to go out alone at night.
In an astonishing move, it also advised women to be accompanied by someone in such areas at all times.
Haze Fan, a passenger on board the flight tweeted a picture of the magazine, asking what London Mayor Sadiq Khan thought about it.
Ealing and Southall MP Virendra Sharma has written to the Chinese Ambassador asking for an apology for referring to London's multicultural community in an "untrue" way.
In his statement to Mr Liu Xiaoming, he wrote: "I am shocked and appalled that even today some people would see it as acceptable to write such blatantly untrue and racist statements.
"I have raised this issue with the Chinese Ambassador, and requested that he ensures an apology is swiftly forthcoming from Air China, and the magazine is removed from circulation immediately."
He added: "I have invited representatives of Air China to visit my constituency of Ealing, Southall to see that a very multi-cultural area is safe, and would be of great value for those visiting London to see."
Mr Sharma also said should this not be addressed in an appropriate way, questions should be raised as to how fit Air China, who fly in twice from Beijing to Heathrow Airport , are to operate in the UK.
Air China later apologised for the article, which it called an "editorial mistake".
